Apple's next-gen iPhone power amp; NASA chemical sensor app

post #1 of 66
Thread Starter 
Apple has reportedly selected a new power amplifier supplier for a new, forthcoming model of the iPhone; and a NASA scientist has used the iPhone to create a chemical sensor.

New iPhone power amplifier

Skyworks has reportedly been tapped by Apple to supply the power amplifier for a new model of Apple's iPhone. According to Taiwanese trade publication DigiTimes, the company orders its parts from Advanced Wireless Semiconductor Company.

AWSC expects its revenues to grow by 50 percent in 2010, when Skyworks reportedly becomes the power amplifier supplier for the next-generation iPhone. No further details on the new hardware were presented.

Recent reports have suggested a new hardware model of the iPhone compatible with the Verizon Wireless network in the U.S. could debut in the summer of 2010. The first three iPhone hardware iterations all saw an annual summer release.

NASA creates prototype chemical sensor

Jing Li, a physical scientist at the NASA Ames Research Center, has used the hardware connectivity made available in iPhone OS 3.0 to create a "compact, low-cost, low-power, high speed nanosensor-based chemical sensing" external attachment. The prototype device, which is said to be about the size of a postage stamp, connects to the iPhone through its 30-pin dock connector.

As first noted by Gizmodo, the device can detect chemicals such as ammonia, chlorine gas and methane. The accompanying application can automatically transfer data to other devices.

"The device senses chemicals in the air using a 'sample jet' and a multiple-channel silicon-based sensing chip, which consists of 16 nanosensors, and sends detection data to another phone or a computer via telephone communication network or Wi-Fi," NASA said.



At Apple's Worldwide Developers Conference in June, Apple highlighted a number of third-party applications that take advantage of iPhone OS 3.0 to connect with external hardware. The new software allows applications on the handset to communicate with external third-party hardware.

The iPhone and iTablet will eventually have a built-in pheromone sensor that will be location detectable and make dating apps more useful, along with all the other chemical / odor sensing that will be incorporated.

In fact these devices will soon take advantage of all 5 senses enhanced and will move into what is now called extrasensory perception but which soon will have a scientific understanding and be used in apps.

I'm little lost of why companies are not making all the things apple promised will be attached to iPhone. I remember when 3.0 came out Apple demoed so many plug ins and extensions like these and looks like companies are way behind that.

It was suppose to be the next big thing for iPhone. Maybe Apple got their hopes too high.

They only demonstrated a few. I have one that wasn't demonstrated, but has just come out. There are a bunch of things out now.

But remember that as hardware is part of this, there is a development time for that, which in the case of some things is more difficult than the software development. Then it has to have prototypes made and tested. Then it must have a production design. Then it must go to production, packaging, etc.

This can take a year or more, whereas a small program can be whipped up within a week. Since OS ver 3, which first allowed these hardware devices to become possible only came out in mid June of this year, the 10 or so devices that are out now are a pretty good indicator of what's to come.

They could make some sweet apps for that!

“What’s That Smell?”

You feel like sushi, so you look it up in the Maps app and find the nearest. In the hallway by the kitchen is a horrific odor. What could it be? A backed-up toilet? Rotten fish recycled with extra wasabi? A waiter with a fungal infection? Did your own left leg die of gangrene? There’s an app for that!

I agree—it’s really weird, when you look at all the zillions of bizarre hardware devices that iPods have always had (I have a laser pointer powered by my iPod Photo). You see plenty of charging and audio dock devices, but other, more creative things have taken a surprisingly long time.

You may be saying that as a joke, but it's not, really. I've read articles in my journals, that they are working on just those very functions. There are specific molecules that indicate infections, and other serious problems. Sensors are being developed to detect that.

They are working on sensors to be placed in food packages which will show if the food is beyond its safe limits, or their smell and taste optimum. This is a very serious industry, and it's thought that it will revolutionize many areas of health and safety.

Development takes time. Especially with hardware.

The iphone morphs into a tricoder.

Maybe the tablet should be itricode, could have multiple levels of meaning.

Could AI please stop it with the pseudonyms? Maybe you think this is subtle hint to set your readers' expectations. Reader sees author's name, reader adjusts expectations. Cute. Ok, here's what I expect:

Daniel Eran Dilger - Full on, unabashed "Apple is right. Here's why" rant
Prince McClean - Supposed straight report, with only required digs and catcalls
Slash Lane - Quick, hard hitting rumors and nonsense

Everyone could make these associations, or maybe instead, AI could use a simple keyword right in the title. (Report, news, rumor)

I'm surprised companies like EA hasn't brought out a game controller. I would think that would help them to sell even more games.

Just say no to MacMall.  They don't honor their promotions and won't respond to customer inquiries.  There are better retailers out there.

Huh! I've seen some others, but not that one.

I just went to the site. This is from the company that's been working on one for quite a while, but couldn't get it working properly. I suppose the new OS ver 3 finally has allowed this. I did like the older design better, as it's smaller, and slicker looking.

Generally speaking, it is a circuit that takes a wimpy analog signal (from a D/A converter circuit, for example), and makes a strong signal capable of driving headphones or speakers.

Apple need to rename the iPhone or just have 2 models; one for regular people and another for Science/Geeks.

What is going to do next? Light up a cigarette?

And then who knows what the CIA, NSA, KGB, MASSOB, and other intelligent agencies have cooked up with it. Plenty enough, I bet you.

Your hands were naked?

Anyway, this would be cool for me to detect refrigerant leaks in piping. I could forego my leak sniffer. Also, at the firehouse, where we use CO detectors and such. Pretty sweet to lose yet another device, and only have to have my iPhone on me.

Is there anyone with even half a brain or a quarter of an education at AI? Repeat after me: plurals of nouns in the English language are not formed with an apostrophe and the letter S. Never. Not ever.

Singular: amplifier.
Plural: amplifiers.

What...the...hell? The CIA? I'm sure their tech is far more advanced than the iPhone.

If you're not a geek, why in the heck would you even want an iPhone? If you just want a cell phone, you could get one. It's a lot lighter on the monthly wallet extraction.

Meh, go read the WSJ and leave us to our comment'''''''''s would ya. It's not like the forum posts look like the ones on YouTube for crying out loud. They are still perfectly legible. Does it really matter if one writes its or it's or not? No. After all, it's how the English language has evolved over the centuries, by people changing the words and the way they are used.

True dat but it gives you crede to argue on the iPhoneInsider.

This may be hard for you to understand from what I read of your statement, but most people who have iPhones are anything BUT geeks.

Hmm - if you have a personal RFID chip - it could automatically unlock the device only when used within range of you - meaning that for someone to steal the device the only value it would have would be the hardware - stealing information or using up cell minutes etc would be far more difficult.

Or combined with RFID tags in the food spoilage scenario could detect a problem and send out a message that would alert other folks buying products from the same batch.

I think mbmcavoy has it right about the power amplifier. A good "amp" as they are called shorthand can make a world of difference in how good your music will sound; whether it's being listened too with headphones or a larger speaker system. Hopefully Apple has chosen another good one. Anyone familier with Skyworks, and whether they make good amps?

An elderly gentlemen I ride the train with everyday is blasting his Frank Sinatra from his iPhone. And by blasting, I mean I can hear it as clear as if I was wearing the headphones. I see more of these type of people than I do "geeks."

On a side note, I lol'd at the big Psystar ad at the bottom of my page.

Well I know what an amplifier is, I just never knew there was one in a phone or really thought about it. The "article" is short enough as it is and somewhat cryptically talks about chips and suppliers of power amplifiers in "new hardware." A short sentence telling us what they are talking about in the context of the iPhone or phones in general would seem to be in order, but I've already spent the ten minutes to look it up at this point.

I find that generally speaking except for the prince McClean stuff, the articles here are sloppy and quickly written without any real care as to what they are trying to explain. Given that the majority of them are shorter than many of the posts that follow, I think spending more than a minute or two on writing the things might be advisable. It's not like it's hard work to write even an extra paragraph or two, let alone a single extra sentence.

Edit: actually it seems like adding the single word "the" before "power amplifier's" in the first sentence would clear up most of the confusion. So that's even less extra work than I thought.

It's not like it's hard work to write even an extra paragraph or two, let alone a single extra sentence.

Let's see if I can help.

In the contest of the phone, an amplifier needs to deliver a fairly small amount of power, as defined in watts. So maybe it may need a half watt output per channel.

That's enough to drive the tiny speakers, as well as headphones.

There are two kinds of amplifiers. One is a voltage amplifier, normally thought of as a pre-amp. That takes the very small voltages present and raises them high enough for further use. Pre-amps rarely can drive headphones directly, though a few can.

That voltage is then current amplified. In other words, the amount of amperage is raised. voltage times amps is watts.

While high impedance devices such as what's found internally in a device can be driven by voltage, low impedance devices such as speakers and headphones need current.

Impedance is simply resistance and capacitance. Not important to understand that completely. But, when it's low, current is needed, when it's high voltage works.

Normal speakers and headphones have wire wound devices that have low impedance. So need some wattage.

I hope that was fairly clear. If not I'll try to explain.

maybe they are not talking about the iPod/sound functions but the wireless carrier signal and amplification of a signal to improve coverage and performance of the wireless data link

Cool looking UI for this app. Didn't know NASA had it in 'em. It's exciting to imagine what apps are just around the corner with the world's best platform for developers...
